CAR BODY BOLSTER.

SPECIFICATION forming part of Letters Patent No. 640,827, dated January2, 1900.

Application filed October 30,1899. Serial No. 735,277. (No model.)

T 66 whom it may concern.-

Be it known that I, MORSE B. SCHAFFER, a citizen of the United States,residing at St. Louis, in the State of Missouri, have invented a new anduseful Improvement in Car Body- Bolsters, of which the following is aspecification.

This invention relates to an integral bodybolster for railroad-cars, andis an improve- IO ment on the body-bolster for which I obtained LettersPatent in the United States, dated June 6, 1899, No. 626,445, for animprovement in car-transoms.

This invention has for its object to increase 1 5 the rigidity of thebody-bolster and to insure a positive and uniform distribution of thestrain of the draft-gear thereto.

The invention consists in features of novcity, as hereinafter describedand claimed,

reference being had to the accompanying drawings, forming part of thisspecification, whereon- Figure 1 represents a transverse section throughthe sills of a railroad-car with my improved body-bolster, shown in sideelevation, applied thereto; Fig. 2, a top plan of the body-bolster; Fig.3, a longitudinal vertical section through the body-bolster andtransverse section through the car-sills on line 3 3 in Fig. 2 5 Fi 4t,a transverse section through the body-bolster longitudinally to the caron line 4: 4. in Figs. 1 and 2; Fig. 5, an end elevation of thebody-bolster as seen from the side of the car, and Fig. 6 a transversesec- 5 tion through the body-bolster longitudinally to the car on line 66 in Figs. 1 and 2.

Like letters and numerals of reference denote like parts in all thefigures.

My improved body-bolster A is composed 0 of two horizontal side platesto, which are arranged transversely to the car at a suitable distanceapart and bear against the under sides of the inner car-sills l 2 3. Theside plates a are united at their ends by plates 1),

which are at right angles to the side plates a and in the samehorizontal plane therewith and bear against the under sides of the sidesills at, the plates 0. and 73 forming a rectangular-shaped frame whichpractically corresponds to the top plate or arch-bar of an. or-

dinary car body-bolster,

Midway between the side plates a and parallel thereto, respectively, isa beam or girder 0, arranged transversely to the car and united at itsends to the end plates 1). The girder c at its middle portion bears atthe top against the under sides of the inner sills l and is preferablyI-shaped thereat in cross-section, having the top and bottom flanges 5,vertical central web 6, and terminal walls 7, which unite with the topand bottom flanges 5 and web 6 and preferably extend therefrom acrossthe spaces between the girder c and the side top plates to and beneaththe latter, to which they are united and serve as braces thereto.

Through the center of the middle portion of the girder c is formed thevertical hole 01 for the king-bolt, (not shown) and beneath the bottomflanges 5, around the hole (Z, is formed the center plate 6 for engagingthe truck-bol- 7o ster in the usual Well-known manner.

From the end walls 7, respectively, of the middle portion of the girderc extend, preferably, two parallel vertical webs 8, the upper edges orsurfaces whereof are horizontal and preferably in the same plane as thecorresponding surfaces of the top flanges 5 of the middle portion of thegirder c and the side and end top plates a Z) and bear against the undersides of the car-sills 2 3, the bottom edges or surfaces of the webs Sinclining upward or diminishing in depth from near the end walls 7 tothe junction of the webs S with the end top plates b; or in lieu of twowebs 8, as shown, one web only or more than two webs may be used. Thewebs 8 are united to the adjacent side top plates Ct, respectively, byvertical braces or strengthening-ribs 9, disposed along the body-bolsterA beneath the car-sills 2 and a or otherwise, as desired. Immediatelybeneath the car-sills 3 the webs 8 are united at the top by cross-bars10, which correspond in width to and bear against the under sides of thecar-sills 3, respectively. From the cross-bars 10 the webs S incline up-5 Ward at the top toward the side sills 4, where they project above theend top plates b and are united thereat to each other and to theplates 1) by vertical. cross-bars 11, forming lugs, which butt againstthe inner sides of the mo side sills e and serve to strengthen the partsand check the end thrust of the body-bolster.

hole d and constitute the side bearings of the.

body-bolster A.

Between the end walls 7 of the middle portion of the girder c and thecentral hole 01 for the king-bolt are two parallel webs or walls 14,which intersect the vertical web 6 at right angles thereto and unitewith the top and bottom flanges 5. The webs or walls 14, which areopposite to each other at an equal distance, respectively, from thecentral hole 01 extend from one side of the vertical web 6 across thespace between the girder c and the" corresponding side top plate a andbeneath the latter to a suitable distance beyond its outer edge, wherethey are united, preferably at the bottom, by a floor 15 and at the rearby. -a vertical web or partition 1 6, which is united 5 at the top tothe said plate a; or in lieu of the floor 15 these extended portions ofthe walls 14 may be closed at the top only, or they may be left open atthe top and bottom, asdesired.

On the inside faces, respectively, of these ex-.

tended portions of the walls 14 are formed two vertical lugs 17, thewhole forming a pocket at for receiving and guiding the strap draw-barf, with its followers g, springs h, and draw-bar bolt 2', of theordinary-coupler draw-bar, as indicated by broken lines, in a similarmanner to the separate castings, with their lugs and guides, now usedforthat purpose and which have hitherto been bolted to the ordinarydraw-timbers. The walls of the pocket at are preferably braced at thetop by horizontal flanges 14', which unite the said walls externally tothe outer edge of the top plate aadjacent thereto, the upper and undersides of the flanges 14 being flush with the corresponding sides of thesaid plate. The walls 14 extend from the other side of the vertical'web6 across the space between the girder c and the corresponding side topplate a and terminate beneath the latter, as in the case of the endwalls 7 of the middle portion of the girder 0. These extended portionsof the walls 14 are united beneath the said plate a by a vertical web18, which may be connected to the corresponding web of the body-bolsterat the other end of the car by the bolt 19, as indicated by brokenlines.

In case it is desired to use the ordinary draw-bar springrpocketattached to the drawtimbers in the usual manner in lieu of the draw-barspring-pocketzr, as above described,

the draw-timbers may be inserted within the recesses y, formed,respectively, in the body-bolsterAbetween the extended portions of theWalls 14, inclosing the pocket rand the corresponding parts of the endwalls 7 of the middle portion of the girder c, as indicated by brokenlines, in which case the rear ends of the draw-timbers 70 will buttagainst the vertical web 6 of the girder 0.

Through the side top plates a and end top plates 1) and through the topflanges 5 and bearing-bars 10 of the girder c are formed holes 20, whichare suitably disposed for receiving the bolts (not shown) by which thebody-bolsteriA is secured to the car-sills. Similar bolt-holes 21 areformed through the strengthening-flanges 14 of the pockets m forreceiving the bolts (not shown) by which the flanges 14 are secured tothe corresponding car-sills 1 and by which, in conjunction with thebolts through the corresponding holes 20 of the top flange 5 and topplate a, the draw-timbers 7c are secured to the sills 1 when thedraw-timbers 7t are used in lieu of the pocket 03, as before mentioned.Holes 22 are also formed through the walls 14 and 'through the oppositeextended portions of the end walls 7, respectively, for receiving thebolts by which the draw-timbers 70, when used, are secured within therecesses 'y.

The body-bolster A, with the combined draw-bar spring-pocket and all thevarious parts formed and arranged substantially as hereinbeforedescribed, is made integral throughout and preferably of cast-steel, thewhole forming a rigid and durable structure.

If desired, the parts composing the draw bar spring-pocket a:to wit, theextended portions of the walls 14, with its floor 15, connectin g web16, lugs 17, and strengthening-flanges 14may be dispensed with and thebodybolster used alone in the usual manner.

I do notlimit myself to the specific configuration and disposition ofthe parts composing the girder c as shown on the drawings, as these mayobviously be modified without departure from my invention.

By this invention the strain of the draftgear is distributed through theentire bodybolster and thence through all the car-sills uniformly,thereby steadying thecar and preventing undue and irregular strainsthereon.

Also by dispensing with the separate parts of the ordinary draw-barspring-pocket and their attachments to the draw-timbers and combiningthese parts in a single piece the construction of the pocket issimplified and rendered rigid and durable.
